Walmart's strategy calls for "controlling a significant portion of the retail market in New York City, the largest consumer market in the U.S., and then replicating this strategy in other urban areas," in order to juice its bottom line, AFGNY says.

Sinking its claws into New York City is pretty much a necessity for the retail behemoth. "Walmart has saturated rural and suburban markets to such a degree that it has begun to cannibalize its own stores," says AFGNY.

In order to achieve its average 21percent market share, Walmart would need to open 159 stores throughout all 5 boroughs, "creating devastating effects for local small businesses, communities and workers."

Brooklyn: Walmart's Ground Zero

One scenario projects 114 small format shops, 34 medium format (grocery store style), and 11 supercenters primarily located in the outer boroughs, with more in Brooklyn -- 48 -- than any other borough.

Walmart already has plans to build a store as-of-right in East New York, Brooklyn.

The report suggests that Walmart’s likely plans for expansion in NYC "would dramatically shift the city’s entire retail landscape for the worse."

159 Walmarts in New York City would mean:

A net loss of nearly 4,000 jobs

Over $350 million in lost wages

Over 4,000 Walmart associates in need of public assistance, costing $4 million in taxpayer dollars for health benefits alone

The shuttering of 105 retail businesses due to one Brooklyn Supercenter alone.

One side effect not mentioned in the report would be the loss of tourist shopping dollars. Out-of-towners love shopping at the city's quirky, special-snowflake retailers. If NYC becomes Walmart City, the jazz, zing, pop and wow-factor of New York City retail would be greatly diminished. Tourists can shop at Walmart at home. Not having to shop at Walmart is one good reason to come to New York City.
